Study Notes
Gibbs-Donnan Equilibrium
- Separated solutions by a semipermeable membrane establish equilibrium, distributing all ions across body fluid compartments.
Water
- Essential for physiological processes including nutrient transport, cell volume determination, waste removal, temperature regulation, joint cushioning, tissue and organ protection, food digestion, and weight regulation.
- Compounds in the body must interact with an aqueous medium for proper functioning.
- Body maintains a consistent water level, comprising 60% of the body weight.
- Found in both intracellular and extracellular compartments.
- Intracellular water: Makes up the majority of total body water (60% or approximately 2/3).
- Extracellular water: Accounts for 40% or 1/3 of total body water.
Electrolytes
- Electrolytes maintain electrical neutrality within cells.
- Involved in blood volume and osmotic regulation.
- Contribute to nerve and muscle action potential generation and conduction.
- Regulate myocardial rhythm and contractility.
- Essential for blood coagulation.
- Facilitate ATP production from glucose.
- Act as cofactors in enzyme activation.
- Maintain acid-base balance.
- Mnemonics:
- NaKO (view Cl as “O”) for sodium, potassium, and chloride.
- Mag Ca-Kapatid for magnesium, calcium, and potassium.
- Mag Ca-Zin for magnesium, calcium, and zinc.
Blood Volume Regulation
- Occurs through the regulation of water and sodium levels, which are closely interconnected.
- Sodium is responsible for maintaining blood volume because it attracts water.
- Sodium imbalance directly affects blood volume, impacting blood pressure and circulation.
